Species text
The snail killing fly Psacadina verbekei is widespread in England as far north as Yorkshire and Wales but very local with about 25 known post 1960 sites (Falk, 1991). It occurs in a range of wetland are used including fens, damp heaths, riversides and dune slacks. Standing water is probably a requirement, though records seem to relate to both bog and base rich conditions. The larvae develop as parasitoids of aquatic snails such as Lymnaea and appear to be adapted for life at the margins of aquatic environments. Management should ensure a range of vegetation types including ponds, ditches and their marginal vegetation using rotational management where necessary. Seasonally fluctuating water levels may be important. References
